Computer Problems,won't turn on. HELP

[NAIDANAC A]

This is kinda like the same problem my dad had a few months ago. I woke up today to find the computer turned off, i figured it was a windows update so i just turned it back on. the fans and lights turned on for about 2 seconds and then shuts off.

My dad's problem was a harddrive was corrupt, so that is the first thing i checked and after unplugging both the computer still didn't work. Now i have no idea what to do, but one thing i noticed before was that my computers clock was losing time for the past month, and it was very noticable yesterday. it became a day behind so i switched it to the right time and went off to work. when i got back the computer was now 3 hours behind the time (was gone for 4).

I have a ati 4850 512,
intel e8500
corsair 520w psu
muskin 4gb ddr2 ram
wd 1000gb green
wd 640
and mobo is DFi lan party p35ktrs.


PLease could you give some advice.

*ps sorry about the lack of capitalization, i am on a ps3 and found that if i click shift-(something) it deletes everything i put.

Do you have a PSU tester?

No.

Tofay is not my day...PS3 is my only source of internet and entertainment and it's audio won't work...

I'd start by opening it up and making sure all the components are seated correctly. Maybe check for a lot of dust build-up. Maybe see if it will run with as few components as possible. It really could be anything from a bad motherboard to a bad switch.

try taking out the memory and plugging each in one at a time, turning it on in between. It could be a memory problem like I had.

I turned it on with the harddrives, cd drive, and ram disconnected and the same thing happens.
I also switched out the ram to 1 stick and it still doesn't work (I had to rma for this ram...).

Should I disconnect the video card and try that?

Also the harddrives and the dvd drive can run with all the others unplugged...so the psu works a bit.

You guys don't think it might be the mobo battery? As I read somewhere that if your computer's clock is acting up it maybe because of the battery.

Well it bought a new mobo battery and the computer booted. the first screen gave me a bunch of settings and said click f1 to continue, i did so then my computer would not reconize my second harddrive, so i figured if i rebot in windows 7 (on second harddrive) then everything would be ok. so i restart and now nothing is outputted, not through usb or the monitor.

I am going to take tha battery out again and see if it workds this time. Did i need to change something in that first screen with F1 to continue?

Fixed, said it was overclocked...which it wasn't so I went into bios and set everything to default.
